This paper aims to analyze stability of parallel tunnels on each stage tunneling, make clear the relations between and various physical values ground support. The is descussed from point distortional strain energy by stress function bipolar coordinates. preliminaly design method supported shotcrete rock bolts presented. results are applied actual data tunnels, then elastic constant at front tunnel excavation that rear one proposed.
